[0025] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0026] In the present invention, unless otherwise stated, directional words such as "top, bottom" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0027] See also Figure 1 The utility model provides a mobile protection device for the edge of an open-pit mine, which includes a protection net 6, a pair of support pipes 3 and a counterweight platform 2, wherein:

[0028] Each support tube 3 is provided with protective net buckles 4 at the positions of 1 / 10, 1 / 2 and 9 / 10 of the height, and the two ends of the protective net 6 are detachably fixed to a pair of support tubes 3 through the protective net buckles 4; the bottom of each support tube 3 is detachably connected to the counterweight platform 2, and the top is provided with a connecting rope buckle at the position of 29 / 30 of the height, and a connecting rope 5 is connected between the two connecting rope buckles; a universal wheel 1 is provided at the bottom corner of each counterweight platform 2.

[0029] Through the above technical solution, a protective net 6 buckle is set at the position of 1 / 10, 1 / 2, and 9 / 10 of the height on each support tube 3, and the two ends of the protective net 6 are fixed to a pair of support tubes 3 through the protective net buckle 4, so that the unfolded protective net 6 can well hold the personnel and effectively prevent the occurrence of high-altitude falling accidents. In order to improve the overall stability, a counterweight platform 2 is used; in order to achieve rapid installation and disassembly, each support tube 3 is detachably connected to the counterweight platform 2; in order to facilitate the overall movement of the open-pit mine edge mobile protection device and improve the flexibility during use, a universal wheel 1 is set at the bottom corner of each counterweight platform 2. In addition, a connecting rope buckle is set at the top of the support tube 3 at a height of 29 / 30, and a connecting rope 5 is connected between the two connecting rope buckles for hanging a safety belt. The safety belt can further improve the safety and ensure the personal and property safety of the workers at the edge.

[0030] Furthermore, in actual use, when the length of the edge operation is long, multiple open-pit mine edge mobile protection devices can be connected and used for better results.

[0031] In this embodiment, in order to maintain the center of gravity of the mobile protection device for the edge of an open-pit mine and prevent its deviation from affecting its stability and success rate when it catches people, preferably, the support pipe 3 is connected to the center of the counterweight platform 2. In this way, the counterweight platform 2 can always keep the support pipe 3 in the vertical direction, so that the protection net 6 is maintained in a fully expanded state and the catching area is maximized, greatly improving the protection efficiency.

[0032] When the mobile protective device for the edge of an open-pit mine is used to protect multiple personnel, in order to ensure stability and success rate in preventing accidents caused by falling from heights, the mobile protective device for the edge of an open-pit mine preferably also includes an auxiliary counterweight 8 arranged on the counterweight platform 2. The auxiliary counterweight 8 can increase the overall weight of the counterweight platform 2, so that the center of gravity of the mobile protective device for the edge of an open-pit mine moves downward, and the stability is better when it is hit by a person, and the success rate of catching a person is greatly increased.

[0033] In addition, in order to use the auxiliary counterweight 8 more scientifically and effectively, it is preferred that the auxiliary counterweight 8 is multiple and multiple auxiliary counterweights 8 are stacked and arranged on the counterweight platform 2. In this way, the auxiliary counterweight 8 of appropriate quantity and weight can be selected according to the specific needs of specific use, and these auxiliary counterweights 8 can be reused multiple times, saving costs.

[0034] In one embodiment, it is preferred that a long slot is formed on one side of the auxiliary counterweight 8, and the auxiliary counterweight 8 can be placed on the counterweight platform 2 by sleeve-mounting the support tube 3 through the long slot. The use of such a long slot structure not only facilitates the installation of the auxiliary counterweight 8, but also improves the stability of multiple auxiliary counterweights 8 after installation, and is not prone to sliding off. For example, when multiple auxiliary counterweights 8 are stacked and used, the long slots of each auxiliary counterweight 8 can be staggered to achieve mutual squeezing and limiting, so that the installed auxiliary counterweight 8 is not easy to slide off the support tube 3 or the counterweight platform 2 along the long slot, which is safe and reliable.

[0035] In this embodiment, in order to prevent the auxiliary counterweight 8 from being too large in size, thus affecting the surrounding use environment and causing inconvenience to the open-pit mine construction, preferably, the size of the auxiliary counterweight 8 is consistent with that of the counterweight platform 2.

[0036] The connection between the support tube 3 and the counterweight platform 2 can be any common quick-disassembly connection method in the art. However, from the perspective of ease of operation and processing, it is preferred that the bottom of the support tube 3 is connected to the counterweight platform 2 via a thread 7.

[0037] In addition, in order to extend the service life of the protective net 6 and ensure the long-term protection state of the open-pit mine edge mobile protection device, preferably, the protective net 6 is a double-layer net or a multi-layer net. The double-layer net or multi-layer net structure is more stable, can withstand greater and stronger impact force, and has a better protection effect.

[0038] In order to realize flexible movement and stable positioning of the mobile edge protection device for open-pit mines, the universal wheel 1 is preferably a lockable universal wheel.

[0039] While the mobile protective device for the edge of an open-pit mine has strong mechanical strength, its overall weight also needs to be considered to facilitate transportation and handling in an open-pit mine environment. Therefore, the support pipe 3 is preferably a hollow steel pipe. The steel pipe is used to utilize its hard material properties to obtain sufficient mechanical strength to ensure the construction of the overall structure and prevent it from falling apart and losing its protective effectiveness. On the other hand, the steel pipe is a hollow steel pipe, which not only saves the cost of raw materials, but also reduces the overall weight, making it easier to transport and carry on the rugged mountain roads of the mine, achieving multiple goals at one stroke.

[0040] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0042] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
